WOOL-COMBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 240,454., dated April 19, 1881.

Application filed July 2, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES OGRADY, a subject of the Queen of Great Britain and Ireland, residing in Philadelphia, Pennsylvania, United States of America, have invented an Improvement in Wool-Oombin g Machines, of which the following is a specification.

My invention relates to a certain improvement in the Noble wool-combing machine, the

object of my improvement being to permit the ready application or removal of certain parts of the machine, all as fully set forth herein-.

after.

In the accompanying drawings, Figure l, 1 Sheet 1, is a vertical section of sufficient of a Noble wool-combing machine to illustrate my invention; Fig. 2, Sheet 2, an enlarged View of part of Fig. 1; Fig. 3, a sectional plan on the line 1 2, Fig. 2; and Fig. 4a sectional plan on the line 3 4, Fig. 2.

In Fig. 1, Arepresents the main frame, and B the cross-bar, of a Noble wool-combing machine, D being the outer rotating ring resting on a hollow annular box heated by steam,and E E the inner and smaller rotating rings resting upon annular flanges carried by the crossbar B. The ring D and the rings E B have projecting teeth, and the slivers of wool which are drawn from reels X and fed over the ring 0 D are pressed onto the teeth of the rings E by means of reciprocating combs or brushes F. All of the rings are rotated in the same direction, and as the peripheries of the rings E diverge from the ring D, owing to the smaller 5 diameters of said rings E, the wool is combed or drawn out between said rings D and E in a manner readily understood by those familiar with machines of this class. The reciprocation of the brushes F is effected by crank-wheels a, 0 which are driven by belts from pulleys b, carried by a transverse shaft, d, adapted to bearings in the upper ends of columns G G, said shaft cl having a pulley, 61, adapted for the reception of a belt from any adjacent powerdriven shaft. Through the columns G extend vertical shafts e, which are driven by means of bevel-gearing from the shaft d, the lower ends of said shafts e carrying cog-wheels f, whereby, through the medium of pinionsgg, the rotation of the rings D and E is effected. Allof 5 these parts are common to an ordinary Noble wool-combing machine; but in such a machine as now constructed the columns G are in one piece throughout, and the shafts e are likewise continuous, so that when it becomes necessary 5 5 to remove one of the rings E the entire column G and shaft e at that end of the machine must first be removed, this operation necessitating the detaching of the shaft 01 and demanding the expenditure of much valuable time, during which the machine must be stopped. I overcome this difficulty by making the shafts e in two parts, and by dividing the columns G horizontally at the shaft-j oint, that portion of each column which embraces the lower part of the shaft being also divided vertically, so as to form two parts, a: m, which are secured together and to the bar B in such a manner that they can be readily detached from each other and from said bar.

Any desired means of securing the two parts of the shaft 0 together may be adopted, the means which I prefer being a sleeve, m, which is slotted for the reception of feathers on the two portions of the shaft, and is secured to both portions of the shaft by means of screws or bolts n.

When it is necessary to remove one of the rings E in my improved machine, the front half, as, of thelower portion of the column Gis 8o first detached, so as to permit access to the screw n, whereby the lower portion of the shaft 0 is secured to the sleeve m. This screwis removed and the lower portion of the shaft is then free to be lowered vertically through the .85 bar B, after which it only remains to remove the other half, .90, of the lower portion of the column G to permit the free lateral withdrawal of the ring E, after repairing which the parts may be replaced with equal facility, there being no interferences whatever with the upper portion of the column G and the parts carried thereby. The lower portion of each column G may consist of more than two sections, if desired.

I claim as my invention- The combination, in a wool-combing machine, of the frame, the wool-combing or drawing rings D E, and actuating gearing, with a two-part shaft, 6, and a column, Gr, also di- 5 vided into two parts and havingits lower part made of detachable sections, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
